Return movement of the rocker-arm will, therefore, carry the lblank to the discharging polnt where itis receivedby suitable means'v and removed from the machine.v The gasket previously out by the head 19 annular groove 31 still remains between the "cutting rings and is removed therefrom by the knock-out ring 0 the position indicated at (see Fig. 1)

32 when the rings assume Where the rings are. in register with a can top carried by one vof the pockets 21 formed in the turret12. .The knock-out ring is here sufiiciently depressed to remove the gasket from the auf nular groove 31, and the depression is, furthcrmore, sufiiciently great te torce the gasket down into the groove 23 formed in I Figs. l and'12, 'which is pivOtally mounted, as at70., on standard lThese arms are operated by meansloia cam 73 and al .connected Y I of. the cam 41s such that the rocker-,farms 72 shoe 66, against and `forced up into the,

the can end, and as this is directly in' register with the cutting rings the operation of cutting the gasket and insertin the same in the can end is here completed. he knockoutl ring;r is actuated by a rocker-arm 76-70 Fig. l, which is pivotally mounted, as at T7, on one side of a guide arm'78, which in turn is secured upon the base-plate A. The opposite .end ofthe arm is connected with a puslrrol 79, which .in turn, is actuated by a 75 camf 80, Fig.- 4, secured upon shaft 6. 'ngage'ment of the cam with the rod tra-nsmits sutlicient rocking. 'movement to remove the ,gasket from the annula'r groove and also to insert it in the annular groove 23 formed in the registering can-end. From the foregoingdescription it will l.be seen that the shafts 3,`6 and 13, Fig. 4, and the shaft .upon which the fee'd 'roller 25 isrmountd, continuously revolve while the turrets 11 and12, together withthe sev-' .eral rocker-arms are inten'nittent-ly Aoperated by the cams and the Geneva movement.

The can-ends supplied the feedingl mechanism 22 are delivered in such '-a mann'er that sone can-endis deposited in cach pocket'formd in the turret 12, the can-ends resting on the table 20. As each pocket containing. a can-end arrives at the positionlb1 dicated at 75 a. V set;y of ringsrontaining a gasket will also be; in registering position to deposit or. insert the-same in thecan-end groove'. l A continued intermittent movevment of the turrent 12 will thennbring each successive pocket into register-witha discharge chute 81 extend ing under a turntable where the ends drop through 'the yturntable r./pioclret into the chute. Since-'for one reason joie-another an end might stickin the-pocket,

means are provided to -insure that the ends are4 removed from the turntable at this point. This means consists of a rocker arm 82 provided at its outer end with three fingers 83. The arm' Ais operated by the push rod 79 and cani 80 and when the rocker arm 110 is ydepressed `by the push rod the lingers 83 engage the can-end 4and force it out of the pocket into the chute.

Referring to Fig. 1, it will be seen tlmtthe strip of conformable material 24. which is intermittently fed bythe feed rollers 25 and 26, after passin over the cutter head, is discharged from t'iemachine as a waste strip as circular openings 84 are formed in the strip when the gaskets and center blanks are cut out. i i

Aspreviously described, the inner blanks 62 are carried by the turret and the suction cups to the position indicated at 60 where they nre removed by the shoe 66. Practically speaking, it is necessary to maintain :i continuous vacuum in the suction cup to preventthe center blank from falling,r aivay from the cup before it reaches the discharging position. Means for maintaining a vacuum in eech cup it passes troni the cutter head into the discharging position shown in Figs. 1, 6 und 16. This mechanism consists of the ring '11 secured on top of the turret 11, and formed in said ring isn plurality of ports 88, one for each set of cutting rings, and each port registers with o. pipe 42, which, es previously described, registers with a; port 30 connected with en 10 nular groove 38.

vMounted on top of the ring 11 is e segment 89 which remains stationery While the ring 4 1 intermittently 'revolves below it. )n the under surface of the segn'ieiit 89 :ire three ulined grooves 1GO, 100a Iand 100', Fig. 16. These grooves are seperated from euch rotherby the narrow dividing Wells 100c :indv as the ring 41 turns under the segment the ports 88 nre brought successively into .register with the-three grooves.- A hole is formed in the segment over cach groove end pipes 893 threaded into the holes. Attached to these pipes ure flexible conductors 90, 91 :md. -92 `which nre connected to u. vacuum pump P. Fig. 16. The conductor 91 is connetted t directly tothe pump and therefore o.- Hvacunrrl is maintained continuously in the'.

groove 1100*. Conductors 90 and 92 are con` nectedtothe valve 93 and the valve is con-` neted tothe pump P by the eonductors'94 and9 5 rReiprocanllyLinoun" d in" the valve l93 it plunger- 96. 'The plunger is operated by vmeans of mi `erin 97,.Figz 1,. which is actu# eted bythe cem I9S :formed on the outer edge of the .disk Whichcarries theA crank pin 71.l y, The operationofthe vel-vefwillnow be made;

fclea'r.' l y When thc turn-table .has come torest with -40 oneof the Sets lof cutting `rings in register with the rcutting'hend, the valve-plunger 96 moves toibring` u. port 99y into register with the tivo condilctolstlmnd 95 so that a vacuum is produced in the en, lying over theuncut conformable. materie The saine movement of the 'plunger also uncovers a port 102, through .which the vacuum previ- `fously"existing in the groove 100" and conduc'tor 92 is released.l The longer is now 5u in the position shown 'in-.Flg 16, and the conformable material is held up against the vacuum cup by .the vacuum existing in the conductor 90 nndzconnccted Imssages. next stage includes the cutting of. the gasket und ,the rotation-'ofthe turntable to the next stop. lviththis rotation :i second port 88V is brought into register with the groove 1 00, the first one being brought into connection with groove 100. Thevalve moves again in. the .direction of the arrow during thisV rotation .to` disconnect the conductors 90 and 95.50 that .the suction cup controilcd by the second. port is not vuci'ulmized and there is therefore noprcnmture picking up of the gasket materiel. 'The vacuum in the irst The l 'possibly tearing or wrin ingsame e thin closes `the vent 102 and connects the conductors sind 9 4 through the vport 96'i and 'passage 96b so that the groove 100b is also 7g vacnmnized. Then the turret hes'conie to rest, the valve 96 again moves to position as shown in Fi 16, so thatthe vacuum cup over the cutting head picks up a. fresh secl tion of the gasketv material and the vacuumin the cup controlledl'iy thel oove 100 and conductor is released. he turn-table then moves egein to bring n. third port into register with the groove 100 as before, the second' one ndvnnclng into connection with the groove 10()n und the first one advancing into connection with groove 100b which in the meantiinefhusbeen vacuumized by onother movement of the valve in .the direction of the arrow. lVhen the turn-table stops, the valve moves back tothe position shown in F ig. 16, causing the cup over the cutter head (the third cup in the cycle as above set. forth) todrew up e new portion of gasket materiel und the first cu to'be 90 open to the atmosphere through t e vent 102, thus dropping' the blank. The second cup controlled vby the conductor-91 is kept vucuumized holding the second blank. out. 'Successive movements of the turn-table eachl 95 time bring a new port S8 into connection with the groove and a new suction cup 1 over the gasket material and alsomove'the preceding suction 'cu s ahead one s Each time lthe turn-talle comes to rest t e 10i vulve 96 moves tocause a fresh portion of gasket material to be sucked up against the cutting rings over thebutting hedj and simultaneously l-to release thevaeuum 1n 'the second vacuum cup ahead so that the blank 1'05 held thereby is dropped It should be understood that the vecuumis maintained con- .stx-ip. For the purpose of prevening the edgeof any set of cutting rings from accidentsilly engaging the ed of the strip and strip of sheet steel 103 best shown in Fig.

v3, has been provided. This metal strip cverlies the edge of the strip first "approached by the cutting rings' which are thereby prevented from `catching theedge of thestrip :1nd Vtearing or wrinkling 'the sheet.'

While any suitable form of device muy be provided for the purpose o, delivering individuel cen-ends to the pockets formed in 130 the turret l2 a suitable form of device, such as indicated at 22, has been provided. This devicc consists of an angularly disposed chute'104 to which the can ends are delivered by means of a conveyer belt or other suitable means not 1ere shown. rl`he can-ends enterin the chu e'104 are stacked one on top of te other and they are discharged one by one as the pockets in the turrets 11 and 12 come into register.

The releasin of the lowerrnost can end is accomplished y the following mechanism: Pivotally mounted on each side of chute, as at 105, is a lever '106, and secured on each vlever is a shoe 107 which shoes are So positioned that they will normally engage the lowermost can endg' the vlevers being normally held together by means of a. spring 107. The levers are, however, intermit tently separated sufficiently to disengage and release the lowermost can end to permit it to drop into the registering turret pocket, and thls separating of the nrms'lOG 1s accomplished by a cam 108 which engages a rocker-arm'109. this rockenarm engages a second rockerarm 110, to the o posite ends of which are connected links 1 1, one for each lever 106. As the 1inks 111 are connected to o posite ends ofthe rocker-arni 110, it will e seen that the movement of same will separate the levers 106 and permit the action de- The blanks 62 secured from lthe continuous stri 24 when the gaskets were cut are used w en making smaller skets for smaller sized cans', These lanks are stacked, as indicated in Fig. 13, between -four guide rods 114 and are removed therefrom one by one by means of a plunger head L15. This 'plunger head is provided 'with an oii'set 116 which is just sufficiently deep to receive one gasket,and a .forward movement of the same in' the direction of the`arrowr removes the lowermost blank and ,moves it into the position indicated at 117 where it is received and held by a suction cup of the turret 11. The plunger head 115 is in this instance operate by the crank pin 71 p'reviously described, and the wiper arm or bell-crank63 is o rated by thelsame movement (see Fig. 12

Figs. 12, 13 and 14 are views of the machine shown in Figs. 1, 2 and 3 in which the feeding mechanism just describedis used in place of the paper strip feeding device indicated in Fig. 1.

Referring to Fig. 11, it will' bc seen that the segment 89 is loosely mounted on top of the ring 41 and is only held thereon bv its own weight and the suction produced. The segment is, however, held from tr'aveling with the ring as u'prights 89 have been' provided which proyect through guide arms 89.

The outer end' of cutting.

The starting and stopping of the machine is entirely controlled by a lever 120 which throws the clutch 5 into and out of engagement with the driving pulley 4.

The machine as a whole is comparatively simple in construction and its operation is positively automatic as all movements are timed to coperatc one with the other. Attendants for the successful operation of the machine are not necessaryl as thc paper, together with the can ends, is automotically delivered and discharged and conveyed to points desired by the conve er belts shown.

We wish it understoo that various changes in form, proportions and details of construction may be resorted to within the scope of the appended claims, and that wc do not wish to limit ourselves to the specific design and construction here shown.
